Is Pelvic Lymph Node Dissection Necessary in Patients with a Serum PSA<10ng/ml Undergoing Radical Prostatectomy for Prostate Cancer?

OBJECTIVE: Controversy persists concerning the role of pelvic lymph node dissection (PLND) in patients with preoperative PSA values <10ng/ml undergoing treatment for prostate cancer with a curative intent. The aim of this study was to determine the incidence of lymph node metastasis in this subgroup of patients. METHODS: Patients with clinically localized prostate cancer and a serum PSA<10ng/ml, without neoadjuvant hormonal or radiotherapy, with negative staging examinations who underwent radical retropubic prostatectomy with bilateral extended PLND and with >/=10 lymph nodes detected by the pathologist in the surgical specimen, were included in the study. RESULTS: A total of 231 patients with a median serum PSA of 6.7ng/ml (range 0.4-9.98) and a median age of 62 years (range 44-76) were evaluated. A median of 20 (range 10-72) nodes were removed per patient. Positive nodes were found in 26 of 231 patients (11%), the majority of which (81%) had a Gleason score >/=7 in the surgical specimen. Of the patients with a Gleason score >/=7 in the prostatectomy specimen 25% had positive nodes, whereas only 3% with a Gleason score /=7 in the prostatectomy specimen was 25% after extended PLND. It seems that in this patient group extended PLND, including removal of nodes along the internal iliac vessels, is warranted.

[Radical prostatectomy in the treatment of organ confined prostate cancer]

Open radical prostatectomy represents one possible therapeutic option for treating patients with clinically localized prostate cancer Patient selection and the surgical management have undergone important changes during the last years, resulting in lower morbidity and probably in a better tumor control due to a better standardisation of the surgical technique. Long-term functional outcome regarding continence and potency are of increasing importance and influence mainly the quality of life in these patients. Open radical retropubic prostatectomy remains the gold standard in patients with localized prostate cancer, due to its low morbidity and excellent oncological and functional results. The value of laparoscopic and robotic radical prostatectomy is still discussed controversially. Due to the relative high morbidity during the so-called learning curve and the lack of long-term oncological and functional results, these techniques seem to show less favourable results.

The free radical scavenger alpha-phenyl-tert-butyl nitrone aggravates hippocampal apoptosis and learning deficits in experimental pneumococcal meningitis

The effect of adjuvant therapy with the radical scavenger alpha-phenyl-tert-butyl nitrone (PBN; 100 mg/kg given intraperitoneally every 8 h for 5 days) on brain injury and learning function was evaluated in an infant rat model of pneumococcal meningitis. Meningitis led to cortical necrotic injury (median, 3.97% [range, 0%-38.9%] of the cortex), which was reduced to a median of 0% (range, 0%-30.9%) of the cortex (P<.001) by PBN. However, neuronal apoptosis in the hippocampal dentate gyrus was increased by PBN, compared with that by saline (median score, 1.15 [range, 0.04-1.73] vs. 0.31 [range, 0-0.92]; P<.001). Learning function 3 weeks after cured infection, as assessed by the Morris water maze, was decreased, compared with that in uninfected control animals (P<.001). Parallel to the increase in hippocampal apoptosis, PBN further impaired learning in infected animals, compared with that in saline-treated animals (P<.02). These results contrast with those of an earlier study, in which PBN reduced cortical and hippocampal neuronal injury in group B streptococcal meningitis. Thus, in pneumococcal meningitis, antioxidant therapy with PBN aggravates hippocampal injury and learning deficits.

Good outcome for patients with few lymph node metastases after radical retropubic prostatectomy

BACKGROUND: Conflicting results exist regarding the value of an extended pelvic lymph node dissection (PLND) in node-positive patients undergoing radical retropubic prostatectomy (RRP) for clinically localized prostate cancer. OBJECTIVE: To assess the long-term outcome in node-positive patients who underwent extended PLND followed by RRP. DESIGN, SETTING, AND PARTICIPANTS: A consecutive series of 122 node positive patients with negative preoperative staging examinations, no neoadjuvant hormonal or radiotherapy, and who underwent extended PLND (>/=10 lymph nodes in the surgical specimen) followed by RRP were analyzed. None of the patients received immediate androgen deprivation therapy (ADT). INTERVENTION: All patients underwent extended PLND followed by RRP. MEASUREMENTS: Biochemical recurrence-free survival, cancer-specific, and overall survival were assessed using the Kaplan-Meier technique. RESULTS AND LIMITATIONS: Median prostate-specific antigen (PSA) was 16ng/ml. At pathological examination 76% of the 122 patients had pT3-pT4 tumours, 50% seminal vesicle infiltration. A median of 22 nodes were removed per patient. Median cancer-specific survival at 5 and 10 yr was 84.5% and 60.1%, respectively. In patients with /=3 positive nodes removed, median cancer-specific survival at 10 yr was 78.6% and 33.4%, respectively (p<0.001). After a median period of 33 mo, 61 of the 122 patients (50%) received ADT, particularly those (69%) with >/=3 positive nodes removed. This retrospective study includes a significant percentage of patients with high tumour burden, and therefore may not reflect current patient series. CONCLUSIONS: Patients with /=3 positive nodes, despite extended PLND and despite ADT in 69% of patients.

Radical Verses: Aku Päiviö's Literary Influence on the Finnish Working-Class

Aku Päiviö was one of the most influential voices of the Finnish labor movement in North America—a poet who also wrote plays and novels, and an editor who worked for a variety of newspapers across the United States and Canada. During the height of the Finnish socialist movement from around 1904-1916, Päiviö published a number of poems that identified with the actions and ideologies of the working-class. He also edited for newspapers such as Kansan Lehti and Raivaaja, further extending his literary reach. Despite his prodigious publications and influence, however, little of Päiviö’s writing has been translated into English. This paper celebrates Päiviö’s legacy with some English translations of his poems, specifically those commemorating the 1913-14 Michigan Copper Strike, and illuminates how various thematic and structural relationships in these poems relate to the ideologies and movements of the time.
